The invention discloses an elevator safety control method and an elevator safety control device. An elevator comprises braking devices arranged on an elevator car, the braking devices are symmetrically arranged on the outer side face of the elevator car, the control method comprises the following steps that the position of the elevator car is obtained in real time; when the position of the elevator car is lower than a preset position, the elevator running speed is obtained in real time; whether the elevator runs abnormally or not is judged based on the position of the elevator car and the running speed of the elevator; and under the condition that it is determined that the elevator runs abnormally, the braking devices are controlled to execute corresponding emergency braking operation based on the elevator running speed, and the emergency braking operation is related to the braking frequency and/or braking force. The additional braking devices are configured for the elevator car, and the emergency protection is performed on safe operation of the elevator in the final stage of elevator operation, so that the effectiveness of safe braking of the elevator is improved, the use safety of the elevator is improved, and the user experience is improved.

    本发明公开了一种电梯安全控制方法以及电梯安全控制装置,所述电梯包括设置于电梯轿厢的制动装置,所述制动装置对称设置于所述电梯轿厢的外侧面,所述控制方法包括:实时获取轿厢位置;在所述轿厢位置低于预设位置时,实时获取电梯运行速度;基于所述轿厢位置和所述电梯运行速度判断电梯是否运行异常;在确定所述电梯运行异常的情况下,基于所述电梯运行速度控制所述制动装置执行对应的紧急制动操作,所述紧急制动操作与制动频率和/或制动力相关。通过为电梯轿厢配置额外的制动装置,并在电梯运行的最终阶段对电梯的安全运行进行紧急保护,从而提高了电梯安全制动的有效性,提高了电梯使用安全性,提高了用户体验。
